CPU 100% usage

Hello, I'm a Win 7 64 bit user from Hong Kong. My CPU has been staying on 100% since I open the computer, also a "ProcessUsage.exe stopped running" message comes out when I open the computer. If you know the solution, may you kindly reply below? Thanks for your help!

We can run a few scans first and look at installed programs (and problems).
Please download all programs to desktop, unless directed, and Copy and Paste all logs.

Please ask if you are not sure at any time, or do not quite understand what I have posted.
Sometimes it can just be my way of expressing myself in a question or reply.

First -

Download Screen317 Security Check and save it to your Desktop.
* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt
* Please post the contents of that document.
Note:: If a security program requests permission to access the Internet, allow it to do so.

Next -

Please download MiniToolBox to desktop and run it.
Checkmark following boxes:

* Double-click on the Rkill desktop icon to run the tool.
* If using Vista or Windows 7 right-click on it and choose Run As Administrator.
* A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
* If not, delete the file, then download and use the one provided in Link 2.
* Do not reboot until instructed.
* If the tool does not run from any of the links provided, please let me know.

NOTE - If normal mode still doesn't work, run the tool from safe mode.
When the scan is done Notepad will open with rKill log.
Post it in your next reply.
NOTE. rKill.txt log will also be present on your desktop.

•Double click on AdwCleaner.exe to run the tool.
•Vista/Windows 7/8 users right-click and select Run As Administrator
•Click on the Scan button.
•AdwCleaner will begin...be patient as the scan may take some time to complete.
•When it's done you'll see: Pending: Uncheck any elements you don't want removed.
•Now click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
•Look over the log especially under Files/Folders for any program you want to save.
•If there's a program you want to save, just uncheck it from AdwCleaner.
•If you're not sure, post the log for review.
•If you're ready to clean it all up.....click the Clean button.
•After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
•Copy and paste the contents of that logfile in your next reply.
•A copy of that logfile will also be saved in the C:\AdwCleaner folder.
•Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine
•To restore an item that has been deleted (if necessary):
•Go to Tools > Quarantine Manager > check what you want restored > now click on Restore.
